Background: The purpose of this study is to asses the frequency of subclinical pregnancy loss (SPL) among women undergoing controlled ovarian hyperstimulation (COH) and in-vitro fertilization with ICSI. Methods: The study was retrospectively conducted in a private IVF center. SPL was defined by a temporary rise in serum βhCG, along with the absence of signs of intra- and extra-uterine pregnancy by transvaginal ultrasonography. Overall 5273 COH and ICSI cycles with embryo transfer (ET) were segregated according to serum E₂ levels percentiles (-24th, 25th, 74th, and 75th), women age and the type of spermatozoa for assisted fertilization (ejaculated and surgically retrieved). Those groups were assessed for SPL rates.
